humanitaria, a subjectief the Emperor ofl v.ift'ustriaHungary,'*and resldent of `1 Trendelenburgstrasse, Charlottenburg; `near Berf lin, Germany, have'jointly invented a new and lmprovqd Apparatus forTreatingjFabric with Liquids, and l?arti ':ularly 'for Bleaching the Same-fof which the following4 is a specnicationf', I

- This yinvention relates to an improved'ap'' paratus for treating'fabric in rope 'form to the action of liquids and our invention 'particularly consists in' an apparatus for'treating the fabric tothe action of chlorid and acid solutions t e same.

l n order that the` invention'ma 4be more clearly understood, reference wil'be here: inai'ter made tothe accompanying drawin s whereon we lhave shown.A by way of examp e the preferred construction of bleaching ap-y paratus.

l Fi re 1 -is a section through a single bleach3 lng vessel constructed according to our invention. Fig. 2 is aside-view partly in section, showing the contiguous arrangement .ofc-three such apparatus. V Y VReferring to'Fig. 1 of the drawin'gs:'The bleaclfxi vessel comprises a preferably wooden y a moreor leeevertical partition 2, which does not extend entirely tothe bottom of they vessel`,"the partition 2 having .an inclined part 2* the. compartment AA:

' Two pieces of fabricae preferablytreated aimnltaneouely, .each piece being separately Round into rope Vform and the twdpropes to' ther into the compartment an means, .but preferably' by means o the pencation of' German Patent No. 209457 the `fabric: being supportedbelow by the inclined e partition 2. The compartment BI-ispreferably smaller than the compartment and-'serves to receive the fabric as it passes through" the opening C inthe lower part lofthe compartment The' li uid is allowed toente'r the space A in consi erable qugtity. ggd.. simultaneously with the laysfeeinmion or meer haar. i Application and December 2s, 191i.

ing ofthe fabrictherein and .in' order to prevent compression of theffabrlc at the bottom of the compartment A at C and consequent entanglement on passing out there from, liquid is auxiliarily supplied toV the compartmentB by Way of an inlet pipe 3, the liquidvin the vessel 1 overflowing through the overflow openings 4 in the compartment newmedia-m2o, 11913.

eoA

A whichare so arranged that the level of the liquid in the compartment B exceeds that of the liquid in thecompartment A, so as to create a difference in the hydrostatic pressure in the two compartments. By this .zmeans the fabric'is caused to more or less fioat in the liquid in the compartment A and .compression at the lower o'utlet opening ,C

Vvthus avoided while at the same timethe liquid is capable of uniformly lpercolating through the fabric. The liquid 1n the compartment 'A flows out through the slots or openings 4 surroundin the same into a tubeV .l'which returns the liquid to the reservoir 64' and 'which may be controlled hy-a cock l62. The-li uid in the reservoir (54 is pumped upwardly y means Iofgapui'np (33 to the supply pipe 3 and to a pipe (56 supplying liquidto-the feed-tube' 70.' The level of the liquid inthe compartments A and B is regu* lated by opening the cock (S2 while the action of the pumpf remains' unaltered. The diife'rencc in 'the vlevel of the liquid in the two compartments is occasioned by thcresistancc -of .the fabric tothe flow oftheliquid@-- ox 1 separated i'ntotwo'cennpart-` fments A and B The liquid. can be heated either by sup'- plying steam to the reservoir 64' or by caus- `lng the liquid toy traverse a heating element on itsvway from the pum 63. i,

In ordento properly e ect the starting of the lower part of fthe.' comvmovable bottom 67'hinged at. GS'and-held in raised position by a 'tappetfontheftappet sha-ft (59. To set the apparatus in op'eration, i

the moyable b'ottom 67 islo'catedin'` its raised position whilelhe compartments A; and B compartment A and liquid simultaneously supplied to saidA compartment to iill'the 'i sume. Thereupon the pump (33 'is 'set in 'During the operation, the abric is drawn out from vthe compartment B at the same rate' as it is fed into the compartment 'A 10o are empty. The fabric is then laid in-i'h'e l "5 e returned to 4the compartment B by means l of an inclined board 9.' The fabric after being expressed between the rollers 7 and 8 passes 'downwardly into a rinsing tank 10 land over a roller 11v therein and upward again aroundl the pressure roller 8, the fabriobeing wound a few times around the .rollers 8 and 1l. The two ropes of fabric are now separated by rakes 60 and the fabric sprayed on its Way into the tank 10 by water.

jets issuing from a.' water pipe 13, the excess water being thereupon expressed between the rollers 8 and A12.

The pressure roller 8 is preferably stationary mounted in position and constructed of wood while the pressure rollers 7 and 1Q which are preferably constructed of cotton or jute are mounted on oscillating arms 14 and 15 respectively, the arm 14 being capable of oscillating about a fixed pivot 1G while the arm l15 capable of oscillating about a fixed. pivot 17. 1&2 are maintained in contact with the central 'roller 8 bypmeans of an adjustable spring 1&2.

connected at'each end to the oscillating arms 14 and 15 respectively.

On leaving the rollers' 8 and 1Q the fabric may, if desired, pass to a second similar ap-" paratus, as illustrated in F142, which apparatus enables a successive chlorid and acid.

bleachingv process to be carried out inasmuch .is the tank 10 serves only to partlyremove the ehlorid solution.

Referring' to Fig. '2 of the drawings: The

fabric either before or after leaving the" scouring tank arrives in the form of sepa.-

. rate ropes in the washing machine 1),which may also, if desired, serve as an acidif'ving rank. The fabric, indieatml in broken lines in Fig. 1, passes around rollers 2t) and 2l in the u-'ashing tank l.) and then upwardly between pressure rollers 22 to and over a windlng device where it. iswound into a single rope and supplied to yany suitable type of feeding device', in thcvdrawings a pendulating feed-tube Q4 being illustrated. liv this means the fabric is laid in foldsl in the acidifying vessel Zrwhich is of substantially the same construction as the apparatus illus` trated in Fig. l. The fabric sulvje'eled herein f ona period'of-abol-it '-5 minutes "to the action of an acid preferably at a ,temperature of'about. 40 to 50o C. After leaving the rinsing tank 2G the fabric then passes over vrollers 27 and 28 where the ropes are separated and in this separated forni pass,

The rollers 7 and' around the rollers 29 and 30 in a second washing tank 31. From thence the fabric'is expressed between the roller 27 and the,pres sure roller 32 and passes'from thence over a winding device 33 .either direct to the washing tank 41 when not reviouslj7 scoured, or

.otherwise to a second ceding tube.34, which/ lays the fabric in a secondl apparatus' 35 similar to'that described withreference to Fig. 1 and in -which the fabric is subjected to the action of-an alkaline chlorid solution. such as calcium or sodium hyp'oehlorite.

The fabric passes from thence through a rinsing tank 3G and with partof the -chlorid solution still remaining thereon, it is separated by the winding device' 33 into, indi-` vidual ropes which are again united .by means of a winding device 37 which suppliesV the fabric to a third feeding tube 38- delivering the fabric to a third -vessel-39l similar to that described in Fig. 1 inwhich the fabric is subjected to the action of an acid. .Thereupon the "fabric passes through a third rinsing tank 40 andl in a si. milar manner -to that hereinbefore described through 'one or more washing machines '41" and from thence to an expressing device 42." The acid and chlorid solutions' are supplied to the vessels 25, 35 and 39 from a series lof reservoirs 43,' 44 and 45- inounted above'thel machine'and which are adapted to supply the liquid' to the feeding tubes 24, 34 and 38 and to the inlet pipes,46, 47 and 48 of the vessels 25, 3,5 and 3S) respectively, the liquid in the vessels overliowing throughoverfiow openings 4S), 50 and 51 and being from thence returned tothe reservoirs 43, 44 and j 45 respectively by-means of suitable pumps not shown on the drawings. To gently. heat the liquid in the reservoirs 43, 44 and 45 in order Ato arcr-flerate the bleaching operation we have indicated a series'of-vatei' pipes 52 -which may be supplied with warm water from any suitable source..
